❖ Equipment that generates a strong electromagnetic field,
such as stereo speakers (other than speakers that are
connected to the computer) or speakerphones.
❖ Rapid changes in temperature or humidity and sources of
temperature change such as air conditioner vents or
heaters.
❖ Extreme heat, cold, or humidity.
❖ Liquids and corrosive chemicals.
If you spill liquid into the computer, turn off the computer,
unplug it from the AC power source, and let it dry out
completely before turning it on again.
If the computer does not operate correctly after you turn it back
on, contact your network administrator. If your computer still
does not operate, refer to “If you need further assistance” on
page 228 for additional technical assistance.
Important information about your CPU cooling fan
The round cooling fan on the underside of your computer
keeps the central processing unit at a temperature suitable for
optimum performance by drawing outside air into the
computer.
To prevent possible overheating of the CPU, make sure the
cooling fan's air intake is not blocked. The fan draws in air by
creating a vacuum. If the fan is blocked, it could cause the
CPU to run at a lower performance level or cause the computer
to shut down. Loose items such as notebook and tissue paper,
plastic wrappers, or other similar materials can block the air
intake, preventing air from reaching the CPU. Do not use the
computer on surfaces with objects that can be drawn in by the
cooling fan.
